Hi Everyone, I'm looking to move from Classic to Lightning and doing some remediation in a sandbox. Any out of the box ideas on designing a lightning record page with a lot of fields?

The fields are used by agents to call on leads, and populate data captured. Issue is with lightning the screen space is much more limited and its more scrolling vs. classic. We do not have service cloud, we are using Sales Cloud.  I like the side panel to show duplicates and the related lists - just trying to solve for the data capture and make it as easy as possible.

Any potential design ideas? Thoughts? Apps? Thank you!
